Training effectiveness evaluation of helicopter emergency relief based on virtual simulation

Helicopters are playing an increasingly important part in emergency relief, such as earthquake rescue, firefighting and medical transport. With the development of virtual simulation technology, virtual simulation-based training is widely used in the training of the helicopter crew especially for the dangerous and costly missions mentioned above. A complete training effectiveness evaluation method is proposed to evaluate the trainees’ training effect based on virtual simulation in this paper. A key to this method is regarding the complicated process as a discrete event-activity flow system and establishing the evaluation indicator system. Then expert group and Analytical Network Process (ANP) are applied to determine the weight of indicators. When the training data are processed, there is a novel attempt to apply Fuzzy Comprehensive Evaluation (FCE) model to calculate the two categories of indicators. Eventually, an experiment and the analysis were carried out to validate the evaluation method.

基于内禀属性的扇区复杂性评估

为了定量描述空域扇区的复杂性,引入交通内禀性概念,通过计算扇区内航空器间的逼近时间、侵略函数、关系矩阵、相关度函数,建立扇区的复杂性测度模型；并通过仿真算例,对扇区复杂度影响因素进行了分析.研究结果表明:复杂性值大小反映了扇区内飞机数量及汇聚、分散程度,复杂性值曲线拐点数量反映了扇区交通有序/无序程度,复杂性值曲线突变反映了扇区交通数量变化情况,可为管制员的监视和冲突解脱方案选择提供一定支持.

基于离心加速度信息的单站无源测距定位方法

针对只测向（B0）方法具有收敛速度慢、定位误差大等缺点，提出了一种利用角度及其变化率、离心加速度等信息进行单站无源测距定位的新方法。对该方法的单次测距误差进行了分析，经多次测量定位计算机仿真结果表明，该方法比只测角定位方法、角度及其变化率定位方法具有更高的定位精度和更快的收敛速度，并且具有更广的应用范围。

Integrated Safety Culture Model and Application

A new safety culture model is constructed and is applied to analyze the correlations between safety culture and SMS. On the basis of previous typical definitions, models and theories of safety culture, an in-depth analysis on safety culture＇s structure, composing elements and their correlations was conducted. A new definition of safety culture was proposed from the perspective of sub-culture. 7 types of safety sub-culture, which are safety priority culture, standardizing culture, flexible culture, learning culture, teamwork culture, reporting culture and justice culture were defined later. Then integrated safety culture model （ISCM） was put forward based on the definition. The model divided safety culture into intrinsic latency level and extrinsic indication level and explained the potential relationship between safety sub-culture and all safety culture dimensions. Finally in the analyzing of safety culture and SMS, it concluded that positive safety culture is the basis of im plementing SMS effectively and an advanced SMS will improve safety culture from all around.
